David Gerard McDaid (born 3 December 1990) is an Irish professional footballer who plays as a striker and is currently player/assistant manager of NIFL Premier Intermediate League side Portstewart.

Born in Derry, McDaid played for Tristar Boys in the Derry and District League Youth Leagues for a number of seasons. He later joined League of Ireland Premier Division side Derry City, who loaned him to divisional rivals Sligo Rovers for the remainder of the 2008 season on 29 July 2008. He made his debut on 2 August 2008 as a 70th minute substitute for Sean Doherty in Sligo's 1–0 home defeat to Cork City. McDaid's first and only for the club goal came with Sligo's third goal in a 4–0 home win over Cobh Ramblers on 27 September 2008 before finishing the loan spell with nine appearances.

He was loaned out to Finn Harps of the League of Ireland First Division at the start of the 2009 season. He scored on his debut for Finn Harps, with an 84th-minute equaliser in a 1–1 draw at Kildare County on the opening day of the season. McDaid scored twice in 12 appearances for the club before returning to Derry in the summer of 2009. He broke into the Derry first team, making his debut as an 84th-minute substitute for Liam Kearney in a 3–1 defeat away at Galway United on 16 October 2009. His first goal for Derry came in his next appearance, a 2–1 home defeat against his former loan side Sligo, and this was followed by goals in successive games against St Patrick's Athletic and Bray Wanderers. He finished the 2009 season with three goals in five appearances for Derry.

Derry were expelled to the League of Ireland First Division for the 2010 season, with McDaid becoming one of the first four players to sign for the club alongside Shane McEleney, Patrick McEleney and James McClean, having committed to a two-year contract. McDaid scored the only goal in the team's first win of the campaign against Limerick on 12 March 2010. His first senior hat-trick came in a 7–0 win away to Salthill Devon on 1 May 2010. McDaid finished the season with 5 goals in 28 appearances, having competed with Mark Farren for the leading striker role in a 4–4–1–1 formation, as Derry won the First Division title. He started for Derry in their 1–0 win over Cork in the 2011 League of Ireland Cup Final, and finished the 2011 season with 3 goals in 28 appearances.

McDaid signed a new contract with Derry in January 2012, contracting him to the club for the 2012 season. He played in the 2012 Setanta Sports Cup Final, which Derry lost 5–4 in a penalty shoot-out following a 2–2 draw after extra time. His final appearance for Derry came in the 3–2 extra time win over St Patrick's Athletic in the 2012 FAI Cup Final at the Aviva Stadium. McDaid finished the season with 17 goals in 44 appearances and was offered a new deal by Derry, but opted instead to go on trial with English League Two side Fleetwood Town.

McDaid signed for League Two side York City on a one-and-a-half-year contract on 29 January 2013, after the club agreed a small compensation fee with Derry. His debut came as a 67th-minute substitute for Michael Potts in York's 4–1 home defeat to Morecambe on 2 February 2013. He finished the 2012–13 season with four substitute appearances for York before he was released by mutual consent on 25 June 2013.

McDaid re-signed for former club Derry City on 1 July 2013, saying "Other clubs expressed an interest in me but I wouldn't play for any League of Ireland club other than Derry City – I'm happy to be turning out for my hometown club again." He made his return in a 2–1 defeat away at Shamrock Rovers on 12 July 2013, before scoring in the following game, a 4–2 away loss to Turkish Süper Lig team Trabzonspor in the second qualifying round of the UEFA Europa League on 18 July. McDaid made 16 appearances and scored seven goals for Derry during the remainder of the 2013 season.

He signed for NIFL Premiership club Coleraine on 17 December 2013, although he would not be eligible to play until the following month.
